To all 'whom t may concern.'

Be it knownxt-hatl, GEORGE A. SEIB, citizen of the United States, and resident of Ilion, in the county of Herkimer and State of New York, have invented certain new anduseful Improvements in Type-VVriti-ng Machines, of which the following is a specification.

My invent-ion relates to typewriting machines.

The principal object of the invention is to provide an 'improved card holder for roller platen machines, to grip the edges of cards, stiff paper, etc.

One of the improvements consists in making better provision than has usually been made for handling the ftabs'that are frequently put on the edges of cards.

Other improvements will be understood from the detailed description of the device.

My invention consists in certain features of construction and combinations and arrangements of parts all ofwhich will be fully set forth herein and particularly pointed out in the claims.

In the accompanying drawings, Figure 1 is a longitudinal sectional view of a platen and some of the associated parts and showing my invention. Fig. 2 illustrates one of the platen heads with a certain plate spring attachedtheretd Fig. 3 is a cross. section through the platen on the line e-x of Fig. 1 and looking toward the right in said ligure. Fig. 4 is a cross section through the platen on the line y-g/ of Fig. 1 and looking toward the right. Fig. 5 is a fragmentary face view of the platen showing part of the slotfor the card clamp. Fig. 6 is a fragmentary view of a set oftab cards. Fig.

7 is an enlarged fore and aft vertical section' through the typewriter lcarriage on the line :zz-:v of Fig. 1 and looking toward the left.

.My ,invention is here shown applied to a Monarch typewriter. yThis machine has a roller platen 1l mounted in end brackets 2 of a carriage 3 which runs on;upp er andlower stationary rails 4, being supported thereon by means of rollersv 5. The platen rubber sheath 7, and said core is supported at' its ends by means of platen heads 8 and .10, the left hand head 8 having crown ratchet teeth which constitute it a line space wheel. A shaft`11 having finger wheels 12 thereon, passes through. the platen heads 8 and 10, and in the standard Monarch construction this shaft is 'journaled in sleeves lixed in the brackets 2 of the carriage. A longitudinal slot 13 is cut through the sheath 7 and wooden core 6 of the platen and, preferably, of a length less than that of the platen; and a gripper made of a sheet metal bar or plate 14, lies in said slot with'suflicient looseness to` enable the bar to be moved in and out. Said bar 14 has a flange 15 bent oft' therefrom which flange is adapted to be pressed against the edge of the card or paper. The bar 14 has` two v.inwardly projecting arms or extensions 16 each of which has/a cross pin 17 therein and projecting therefrom on bot-h sides of the arm. vThe slot 13 is formed with two enlargements 18, one of which'is shown in Fig. 5, the construct-ion being such as to admit of the plate 14 and pins 17 being inserted into the slot 13 from the outside of the platen, the pins being admitted by the enlargements 18. A slight depression 19 in front of the slot .13, allows the flange 15 to have its outer surface about Hush with thatof the platen. On each of the platen heads 8 and 10 thereis mounted a plate spring 20,

said springs being eachbent at right angles Patented May 28,1912.

to form a securing port-ion 21 that lies against the platen head, to which itis fastened by means of screws 22. Each spring 20 consists of an arm extending longitudinally of the platen and formed near its end with an open slot 23, which receives the project-ion .16; and the two branchesl of the spring rest on the pin17. The springs are under tension to draw the' gripper inward to press the flange 15;"ofsa1d gripper into the depression 19 or against t-he card 24, Fig. 7. I

vIt will be seen that` the parts can be assembled by lfirst inserting the plate 14 and then putting in the platen heads, taking care to position the springs properly on the projections 16, the platen heads then being secured in position Vbv means of the usual screws.

In order to move the gripper to release it, the shaft 11 is made movable endwise and provided with cams 25 consisting of tapered collars secured to the shaft by pins`26 and arranged to press against the lower inclined edges 27 of the projections 16, when the shaft is pushed towardthe left 1n Fig. A spring. 28,-coiled about the shaft 11, 1s

compressed between the left-hand platen head and a collar 30 which is secured on the shaft 11, and this spring normally holds the shaft 11 and said shaft is secured to said` platen head by a set screw 31 and the shaft is journalcd 1n a collar` or sleeve fixed in the bracket 2. In the resent construct-ion this platen head is bore out to a larger size. and a sleeve 32, surrounding the shaft 11, passes through both the platen head 10 and the right-hand carriage bracket 2, this sleeve having an external diameter equal to that of the xed sleeve ordinarily employed. This sleeve 32 is secured in the platen head 10 by the set screw 31 so that the sleeve and platen are constrained to turn together. The platen shaft is formed with a feather 33 which plays ina longitudinal slot 34 in the sleeve 32 (Fig. 4) so that the shaft and sleeve are constrained to turn together but the shaft can slide in the sleeve, this motion of the shaft toward the right being limited by the feather 33 striking the end of theslot 34. The sleeve 32 turns with the platen and has a bearing in the'bracket 2.

It will be seen that the card holding platen is a special platen and provision is v sleeve A32 with it; `The collars 25 and 30:

made for readily removingthis platen and substituting in the same machine .a standard platen. This is done by removing the lefthand finger wheel 12 and loosening the set yscrew 3 1, when the shaft can be pulled out,

of the platen toward the right. bringing the are of such diameter that they-can be -withdrawn after the sleeve 32. and the spring 28 can also. When this platen is removed the fixed sleeve can be inserted in the righthand bracket 2 and the standard platen mounted in place in the usual manner. It will be seen that the substitution of this special vplaten for a standard platen. and vice versa, is effected without modifying any of the ordinarv features of the machine. In order to facilitate the withdrawal of the shaft 11 the collars 25 are rounded` oft' at their right-hand ends as shown at 35 and the collar 30 is beveled at 36 to facilitate the drawing of the shaft and collars past the pulse of the spring28. The springs 20 then draw the flange 15 down into clamping engagement with the card. It will be noted that there are two of thesesprings, one near each end of the clamp, and the two ends of the clamp are thus drawn down independently, which ives a more perfect engagement of said c amp on the card.

Some index cards have tabs 38 along their upper edges and these tabs are distributed along the upper edges of the different cards at different points. Fig. 6 indicates aset of cards having tabs at four different positions, one card having a tab at its left-hand end, another card having a tab at its right-hand end, and other cards have tabs in intermediate positions. In order to facilitate'the handling of this sort of cards the bar 14 is formed with several cut-outs or slots 40 so that the tab can be inserted through one of these slots and the straight part of the upper edge-of the card can still be inserted under the flange 15. I have shown four of these slots but of course any suitable number can be provided. The four here shown are designed to t tabs like those shown in Fig. 6. If the tabs come at other positions, however, these slots .will still ordinarily be enough for the purpose, because the card can be moved a suitable distance to the right or to the left so as to bring the tab into one or the other of these slots, the bar 15 being made longer than the cards to allow of such adjustment of the card in a right or lefthand direction. When a card is placed in the clamp, the solid partsof the bar 16, between the cut-outs 40. serve to position and square the card on the platen, and this is true whether or not said card has atab. When a card `is inserted, it is pushed under the flange 15 until its straight upper edge is arrested by said intermediate solid lparts of the bar 16, thus insuring that the upper edge of the card is parallel with the axis of the platen.

The machine shown hasthe usual paper apron 41 and feed rolls 42. The card or paper is secured in the gripper or clamp when the latter is in any convenient position, and the platen is then turned, drawing the card through over the paper apron and feed rolls until the writing line is at the printing point of the machine. Various changes can be made in, the details of construction and arrangement without departing from my invention.
